Hi there! - I know that this function is made in some mods like Better Than Wolves and so on, but I would like to get some of the mechanical functionalities like that saw bench that could split planks etc in half by e.g press Q into the saw (Craftingtable sort of block with a saw on it) Could tools like these be developed as a Bukkit plugin? !!
If you set this as filled that means you have what you were looking for. Did you find it? Also, this is impossible for bukkit you'll need spout.
